MEMPHIS, Tenn. (AP) — A new Tennessee congressional map that carved up a majority Black district in Memphis is making its electoral debut Tuesday in a primary election that will determine the nominees for a Republican attempt at a clean sweep of the state’s U.S. House districts in the midterms.

The primaries were upended just three months before the vote when the Republican-led Legislature redrew congressional districts following a U.S. Supreme Court ruling that weakened federal Voting Rights Act protection for minorities. President Donald Trump cheered the redistricting as part of a national plan to try to help Republicans hold on to their slim House majority.
